Air ducting cover

Abstract

An air ducting cover for guiding a directed flow of air output by rotation of a fan is proposed. The air ducting cover includes a frame for covering outside of the fan and a flexible cover member having a channel formed therethrough for connecting with the frame. By such arrangement, the directed flow of air output by the rotation of the fan can be guided flexibly by the means of the channel. The ducting cover is able to provide flexibility in common use without the need of being re-designed to meet different applications. Further, the flexible cover member can be replaced easily, so as to solve prior-art problems.

1 . An air ducting cover for guiding a directed flow of air output by rotation of a fan, comprising: 
 a frame for covering outside of the fan, and formed with at least one first connecting portion on a surface thereof from which air is output by the fan; and    a flexible cover member shaped to form a channel, wherein at least one second connecting portion is formed at an end of the flexible cover member, for connecting with the first connecting portion, so as to allow the directed flow of the air output by the rotation of the fan to be guided flexibly by the means of the channel.    
   
   
       2 . The air ducting cover of  claim 1 , wherein the frame is a structure having a U-shaped cross section.  
   
   
       3 . The air ducting cover of  claim 1 , wherein the frame is further formed with a folded selvedge on a surface thereof where air enters the fan, allowing an outside edge of the fan to be covered by the folded selvedge.  
   
   
       4 . The air ducting cover of  claim 1 , wherein the frame is further formed with a folded selvedge on the surface thereof where air is output by the fan, and the first connecting portion is formed on the folded selvedge.  
   
   
       5 . The air ducting cover of  claim 1 , wherein the frame is formed with a plurality of first connecting portions on the surface thereof where air is output by the fan.  
   
   
       6 . The air ducting cover of  claim 1 , wherein the first connecting portion and the second connecting portion are respectively a button and a buttonhole.  
   
   
       7 . The air ducting cover of  claim 1 , wherein the flexible cover member is formed with a plurality of second connecting portions.  
   
   
       8 . The air ducting cover of  claim 1 , wherein the end of the flexible cover member is further formed with a leaning portion for leaning against the frame, and the second connecting portion is formed on the leaning portion.  
   
   
       9 . The air ducting cover of  claim 1 , wherein the flexible cover member is a structure having a U-shaped cross section.  
   
   
       10 . The air ducting cover of  claim 1 , wherein a bottom surface of the flexible cover member is formed with a third connecting portion.
